Overtonis is a condition caused by too many sets, too many different exercise combinations – in short – overwork, which causes muscle tissue loss, hormone depletion, weakness and a smoothed-out appearance, inability to produce a pumping effect and general lassitude or weakness.
Overtonis produces a stringy appearance with no healthy round look apparent in a properly worked muscle.
Overtonis is caused by male hormone loss.
Overtonis causes the central nervous system to cease pumping blood into capillaries which might otherwise rupture. To achieve a maximum pump exercise until you notice pump loss. At this point, check back the number of sets, time, tempo and repetitions required to achieve this effect. This is your personal exercise level.
